i have a problem with my BK650_AS

[Anonymous user]

we just replace the battery of our UPS, but its seems they have a prob. intermittent clicking and the Replace Battery LED lit up. i tighten the connector already but still same issue, i removed the battery and transfer the BE500EI and its working fine...i connect one of our pc to the UPS and i unplug the power supply and its working fine.

Any idea whats wrong w/ the unit..

Thanks

Is the replace battery light solid or flashing? Do you have the exact model & serial number on the unit?

Did you mean you swapped the battery into a 500 unit and it works fine there, or did you temporarily replace the 650 with a 500? When you said you pulled the plug on the UPS and the computer stayed on, was that the 650 or the 500?

yeah the replace battery LED is flashing about 4 - 8 flashes, yeah the 500 was fine, i just replace the battery, i try both units to connect to computer and using same battery..and its work fine..

The flashing replace battery light means it thinks the battery is disconnected. If it goes to battery when you pull the plug on the UPS, then it sounds like the battery sensor is just flaky.

There isn't really a way to force it to realize the battery is there if it doesn't see it, so you can either live with it as is, contact Coastal Business Machines (888-234-9877) to look into repair options, or trade the unit in for a discounted brand new one through the [Trade-UPS program|http://buy.apc.com/commerce/storefronts/tradeups/tradein.aspx?storefrontcode=apcetu&countrycode=US&t...].
